This is what I use to make a backup copy of all my images to a temporary folder in Linux. It excludes a number of file extensions, like the ones for movies. It is executed from the folder that contains the files you want to copy.

OPTIONAL install monoBristol, it provides a GUI to Bristol to start up other instruments.

This should give you all you need to start playing your keyboard. However, you would need to start up Jack Audio and Bristol separately every time and also connect your midi keyboard to your synthesizer software and your software to your speakers via Jack Audio each time. Fortunately it is easy to script this in Linux, since there are command line equivalents for all steps.

Here is my script that fires up a Hammond Organ and a Rhodes Bass Piano at the same time 🙂
